If you use Eclipse for Java, you have:
- Debugger in place
- Automatic builder, compile on save
* Jump to line from error list
* Jump to declaration
- Show JavaDoc in tooltip, even in autocompletion
- Show hierarchy tree
- Autocompletion
- Quick assist, e.g.
	- assign ctor parameter to new field
	- extract selected text into local variable
	- Mark source portion, extract to method, the IDE evaluates the needed
parameters and return value
	- ...
There is so much more. But the main thing is, you are not only able to
use grep and friends on the pure text level. With an IDE you have
semantic support. This makes refactoring your code so much easier. You
can say "rename this method" and it works, all references to this method
are also altered. "Move this inner class to a top level class in that
package", "Derive from that class, yes add the needed ctors". There is
even an API to automate refactorings.

I think Descent is the right way. But here, a port of DMD is directly
integrated into the plugin. To put more manpower in this project would
be the best way imo.
